Be it known thatv I, Roy GRINVILI@ SANDS, a citizen ofthe United States, residing at Waukegan, in the county oLake and State of Illinois, have invented new and useful Improvements in Soldering-Irons, of

which the following is a full, clear, concise, and exact description, reference being had -to the accompanying drawing,

fo'rmlng a part of this specification.

My invention relates to solder' -irons and has to do more .particularly with the provision of an adJustable: soldering-tip whereby, as the tip wears olf, it may be adjusted so' as to keepthe extreme end sutably clear of the holder or body portion, y

whichv contains the receptacle for the tip.

'My invention is more particularly useful in connection `with electrical solderingirons, and, although illustrated in connection with'such a device, it is not limited to such a particular application. Other fea-v tures 'of my invention will be vmore particularly pointed out in the ensuing specification and in the appended claims.

For a better understanding of my invention, reference is to be had to the accompanying drawings, in which like reference' characters indicate like parts," and inv which- Figure lis a side elevation of a complete soldering-iron embodying my invention;

. Fig. 2 is a longitudinal cross-sectional view showing more particularly the heatin' element within the outer casing, and the a justable tip;

Fig. 3 is a longitudinal section along the line 3-3 of Fig. 2;

Fig. 4 is a'tra'nsverse section along the line'4--4 of Fig. 3;

l' Specication of Letters Patent.

\trica llyheated unit including. an elementbody or core 2 preferably asteel tube having a mica msulated winding -3 of any of the well-known materials which are adapted for heating purposes. The element-body or core 2 ma be made 'of other material, such as porce am, 1f desired. The rear end of the .receptacle or element-body 2 is reduced, as shown at 4, so asto act as a support for mica washers 5 which are secured thereto by'means of a screw 6, the washers 5 havin holes through which the terminals 8,v 9 0I the coil 3 pass. The outer end of the member 2 is flanged and carries a` pair of ears 10, 11, wh1ch are adapted to set in recesses 12 (Fig. 5) provided in the outer end of the casing 13. This casing 13 lis preferably tubular steel which is reduced at 14 So as to serve as a shank adapted to be inserted in the handle 15. A plate 16 of insulating material is secured in the shank end 14, the terminals 8, 9 of the heating elementbeing `secured to the insulating plate 16. A twostrand cord 17 passes through the handle 15 and is attached to the insulating plate 16 and connected to terminals 8, 9 by means of connectors 18. A lock-washer 19, similar to that shown in Fig. 7 spans the shank 14 and rests against the shoulder at the bottom of the enlarged hole 20 in the handle.

The so dering-tip 1 is adapted lto be inserted in the receptacleA, belng a snug t, so that it is in intimate contact with the member 2, which acts as a core for the heating-element winding 3.

One of the features of my invention is the provision of a simple adjusting means for the tip 1, so that as its soldering end becomes worn olf the tip may be suitably extended -so that it is in a convenient position relative to the receptacle and readily available for use. For this adjusting means, I preferably provide a lock-washer 21 slotted at 22 and adapted to slip over` any one of the pairs of notches 23 in the tip 1. In the assembly views (Figs. 2 and 3) the lockwasher 21 is shown lat the extreme end pair of notches 23, and the tip 1 is inserted in the heating element to its greatest extent, the washer 21 resting against-the outer end of the member 2 andthe casing 13. In order tohold the tin in the receptacle, a threaded collar or nipple 24 is provided. being adapted to beplaced over the end of the tip 1 and 'apparent that the Inorder to adjust the tip, the nipple 24 is removed and the tip 1 with its collar 21 removed from the heating-receptacle A after` which the lock-washer 21 is slipped oli the tip and replaced at the desired pa1r of notches 23. The tip is then again inserted in the receptacle until the collar 21 comes into contact with the end thereof, after which the nipple 24 is threaded onto the casing 13. Thus, it will be apparent that as the natural wear of the tip occurs, or if it is desired to vary ythe adjustment of the tip for other reasons, it may be readily removed and the adjustment of the lock-washer 21 changed, after which the tip' is again inserted and held in place bythenipple 24.

In illustrating my invention, I have shown a preferred form, one that has been found adaptable for commercial purposes, but it will be apparent that my invention is not limited to the particular embodiment shown, and I contemplate applying it in other ways than that illustrated.' Therefore, I do not desire to be limited to the exact structure shown and described, but aim vto cover all that which comes within the spirit and scope of the appended claims.

I claim as new and desire to secure by Letters Patent of the United States:

1. A soldering-iron comprising an elongated tip, a hollow receptacle for said tip, a stop adjustable along said tip in a plurality of positively fixed positionsto vary the relation of said tip and receptacle, and means for holding the tip in they receptacle.

2. A soldering-iron comprising an elongated tip, a receptacle for said tip, a stop, said tip being provided with a series of notches to receive the stop to vary the adjustment of said tip, and means for holding the tip in the receptacle.

3. A soldering-iron comprising an elongated tip, a hollow receptacle for said tip, a lock-washer, said tip being provided with a series of notches to receive the washer to vary the adjustment of said tip, and means for holding the tip in said receptacle.

4. A soldering-ironV comprising an elongated tip, a hollow receptacle for said tip, an adjustable lock-washer for said tip coperative with said receptacle to vary the ex# tending portion of the tip, and means for holding the tip in said receptacle.

5. A soldering-iron comprising an elongated tip, a hollow heating-element receptacle for said tip, an adjustable lock-washer for said tip coperative with said receptacle to vary the extending portion of the tip, and

a nipple coperative with said tip, washer and receptacle for holding the tip in said receptacle.

6. A soldering-iron comprising an elongated tip, a hollow electrically-heated receptacle for said tip, and a lock-washer for the tip coperative with a stop at an end of vthe receptacleto limit the insertion of the tip in the receptacle, said tip being provided with a series of notches to receive the lockwasher to vary the adjustment of the tip.

7. A soldering-iron comprising ari elongated tip, a hollow electrically-heated receptacle for said tip, a casing for the receptacle, an adjustable lock-washer for the tip, and a nipple adapted to thread onto the ca sing and coperative with the lock-washer Jfor holding the tip.

In witness whereof, I have hereunto subscribed my name. l
